This Course provides a summary of the significant changes, for chapters 3 and 4, of the 2014 National Electrical Code®. With every new edition of the NEC, some of the changes include new requirements to sections, while some of the changes include entirely new articles. Some changes are revisions to existing requirements while others are deletions to some existing requirements. To view these changes in detail, please take the “2014 NEC Changes” courses.
Although not required, it is recommended to have a copy of the 2014 NEC manual for reference, especially when reviewing information in large tables.
Chapter 3 covers wiring methods and materials, and provides some very specific installation requirements for conductors, cables, boxes, raceways, and fittings.
Chapter 4 covers regulations dealing with equipment for general use.
